About this Dataset

US Tornado Dataset 1950-2021

Introduction

Tornadoes frequently occur in the United States, resulting in vast destruction and often injuries and death. They occur more often in the United States and Canada than in other countries with the most tornado-prone regions in the US being the central and southeastern states along a corridor sometimes called "Tornado Alley."

A tornado's destructiveness is derived largely from the wind speed within it. For this reason, meteoroligists rate tornadoes using a scale based on wind speed. In the US, tornadoes were originally rated on the Fujita Scale, and since February 2007 on the Enhanced Fujita Scale. The two scales cover slightly different speed ranges, but for practical purposes are the same. The enhanced Fujita scale is shown below.

The Enhance Fujita Scale

Rating	Wind Speed	Damage
EF0	65–85 mph	Light damage
EF1	86–110 mph	Moderate damage
EF2	111–135 mph	Considerable damage
EF3	136–165 mph	Severe damage
EF4	166–200 mph	Devastating damage
EF5	>200 mph	Incredible damage

Origin

This dataset was derived from a dataset produced by NOAA's Storm Prediction Center. The primary changes made to create this dataset were the deletion of some columns, change of some data types, and sorting by date.

Column Definitions

yr - 4-digit year
mn - Month (1-12)
dy - Day of month
date - Datetime object (e.g. 1950-01-01)
st - State where tornado originated; 2-digit abbreviation
mag - F rating thru Jan 2007; EF rating after Jan 2007 (-9 if unknown rating)
inj - Number of injuries
fat - Number of fatalities
slat - Starting latitude in decimal degrees
slon - Starting longitude in decimal degrees
elat - Ending latitude in decimal degrees (value of 0 if missing)
elon - Ending longitude in decimal degrees (value of 0 if missing)
len - Length of track in miles
wid - Width in yards
